Training in endocrine surgery

Background/purpose In Europe, the Division of Endocrine Surgery (DES) determines the number of operations (thyroid, neck dissection, parathyroids, adrenals, neuroendocrine tumors of the gastro-entero-pancreatic tract (GEP-NETs)) to be required for the European Board of Surgery Qualification in (neck) endocrine surgery. However, it is the national surgical boards that determine how surgical training is delivered in their respective countries. There is a lack of knowledge on the current situation concerning the training of surgical residents and fellows with regard to (neck) endocrine surgery in Europe. Methods A survey was sent out to all 28 current national delegates of the DES. One questionnaire was addressing the training of surgical residents while the other was addressing the training of fellows in endocrine surgery. Particular focus was put on the numbers of operations considered appropriate. Results For most of the operations, the overall number as defined by national surgical boards matched quite well the views of the national delegates even though differences exist between countries. In addition, the current numbers required for the EBSQ exam are well within this range for thyroid and parathyroid procedures but below for neck dissections as well as operations on the adrenals and GEP-NETs. Conclusions Training in endocrine surgery should be performed in units that perform a minimum of 100 thyroid, 50 parathyroid, 15 adrenal, and/or 10 GEP-NET operations yearly. Fellows should be expected to have been the performing surgeon of a minimum of 50 thyroid operations, 10 (central or lateral) lymph node dissections, 15 parathyroid, 5 adrenal, and 5 GEP-NET operations.Funding Agencies|Linkoping University</p

Intraoperative neuromonitoring of the RLNs during TOETVA procedures

WOS: 000514839400008PubMed: 32175253Transoral endoscopic thyroidectomy by vestibular approach (TOETVA) is now being performed in increasing frequency and getting more and more attention. TOETVA is carried out through three incisions in the oral vestibular area. Thyroidectomy is performed endoscopically using conventional laparoscopic instruments, an energy based device and neuromonitoring instruments. Intraoperative neuromonitoring is one of the tools of utmost importance, used for navigation and confirmation of the functional integrity of the recurrent nerve during TOETVA. the aim of this study is to give information about the standards and technique of intraoperative neuromonitoring of the recurrent laryngeal nerves during TOETVA procedures. TOETVA is a safe technique with no visible scarring and hence resulting in an excellent cosmetic effect. We believe that neuromonitoring of the recurrent laryngeal nerves also minimizes the risk of nerve damage and is an essential safety component in this technique

A nomogram to predict the likelihood of permanent hypoparathyroidism after total thyroidectomy based on delayed serum calcium and iPTH measurements

Background: Retrospective studies have shown that delayed high-normal serum calcium and detectable iPTH are independent variables positively influencing outcome of prolonged parathyroid failure after total thyroidectomy (TT). The aim of the present study was to examine prospectively the ability of these two variables to predict permanent hypoparathyroidism in patients under replacement therapy for postoperative hypocalcemia. Methods: Prospective observational multicenter study of patients undergoing TT followed by postoperative parathyroid failure (serum calcium <8 mg/dL within 24 h and PTH <15 pg/mL 4 h after surgery). Serum calcium, vitamin D and iPTH were determined before thyroidectomy, 24 h after surgery, at 1 month and then periodically until recovery of the parathyroid function or permanent hypoparathyroidism was diagnosed after at least 1 year follow-up. Results: Some 145 patients with postoperative hypocalcemia were investigated [s-Ca24h 7.5 (0.5) mg/dL]. Hypocalcemia recovered within 30 days in 91 (63%) patients and 54 (37%) developed protracted hypoparathyroidism {iPTH 5.8 [4] pg/mL at 1 month}, of whom 32 recovered within 1 year and 22 developed permanent hypoparathyroidism. Protracted hypoparathyroidism was related to few parathyroid glands remaining in situ (PGRIS). Serum calcium concentration (mg/dL) at 1 postoperative month correlated positively with the rate of recovery (percent) from protracted hypoparathyroidism: 10 (83%) (P=0.013). Serum iPTH at 1 month was also higher (7.3 vs. 3.7 pg/mL; P=0.002) in recovered protracted hypoparathyroidism. The combination of both variables predicts the likelihood of recovery of the parathyroid function with >90% accuracy. Conclusions: High-normal serum calcium and low but detectable iPTH concentrations at 1 month after TT were associated with better outcome of protracted hypoparathyroidism. A nomogram combining both variables may guide medical treatment and monitoring of post-thyroidectomy prolonged hypoparathyroidism

International neuromonitoring study group guidelines 2018: Part II: Optimal recurrent laryngeal nerve management for invasive thyroid cancer-incorporation of surgical, laryngeal, and neural electrophysiologic data

The purpose of this publication was to inform surgeons as to the modern state-of-the-art evidence-based guidelines for management of the recurrent laryngeal nerve invaded by malignancy through blending the domains of 1) surgical intraoperative information, 2) preoperative glottic function, and 3) intraoperative real-time electrophysiologic information. These guidelines generated by the International Neural Monitoring Study Group (INMSG) are envisioned to assist the clinical decision-making process involved in recurrent laryngeal nerve management during thyroid surgery by incorporating the important information domains of not only gross surgical findings but also intraoperative recurrent laryngeal nerve functional status and preoperative laryngoscopy findings. These guidelines are presented mainly through algorithmic workflow diagrams for convenience and the ease of application. These guidelines are published in conjunction with the INMSG Guidelines Part I: Staging Bilateral Thyroid Surgery With Monitoring Loss of Signal. Level of Evidence: 5 Laryngoscope, 128:S18-S27, 2018

International neural monitoring study group guideline 2018 part I: Staging bilateral thyroid surgery with monitoring loss of signal

This publication offers modern, state-of-the-art International Neural Monitoring Study Group (INMSG) guidelines based on a detailed review of the recent monitoring literature. The guidelines outline evidence-based definitions of adverse electrophysiologic events, especially loss of signal, and their incorporation in surgical strategy. These recommendations are designed to reduce technique variations, enhance the quality of neural monitoring, and assist surgeons in the clinical decision-making process involved in surgical management of recurrent laryngeal nerve. The guidelines are published in conjunction with the INMSG Guidelines Part II, Optimal Recurrent Laryngeal Nerve Management for Invasive Thyroid Cancer–Incorporation of Surgical, Laryngeal, and Neural Electrophysiologic Data
